Long film showing all the ins and outs of how a car works.
Reel 10. The springing system is described. Its location is shown on drawings. Strain acting on the frame when the car is in motion is demonstrated. "Weaving" and "lozenging" are illustrated. The 'modern' X braced frame is shown. Various drawings show how springs are used to absorb road shocks. C/U of nuts and bolts holding the springing system to the chassis of the car. Car on its side to show the springing system. C/U of the springing system moving and of the shackles which bind. Five best known types of spring are described and illustrated. The latest idea - torsion rod springing is explained. A cartoon door is seen opening and closing to show the torsion rod. This principle is applied to the back axle. "Blue Bird" mentioned in an intertitle as using this kind of spring. Shock absorbers are described and illustrated. Film ends with first a stationary shot of a car (Morris of some type) then shot of the car driving away from the camera down a country road.
Note: the original title "The Romance of the Motorcar" was replaced a couple of years later by a new title: "The Motorcar and its Mechanism." on the negative. Some scenes are different but basically the same film- check record for negs. Seems to be an instructional film for students of motor mechanics.
